Abstract
The invention discloses a coreless rewinder using airflow for winding. A winding guide face close to the roller face of an upper rewinding roller is arranged below the upper rewinding roller. A winding channel is formed by a gas between the roller face of the upper rewinding roller and the winding guide face. A blowing pipe is arranged below the upper rewinding roller. The flowing direction of the airflow of the blowing pipe in the winding channel is opposite to the advancing direction of paper in the winding channel. The invention further discloses a winding method of the coreless rewinder. During winding, blowing is conducted towards the winding channel so as to make paper sent successively be stacked in the winding channel, and thus the stacked paper in the winding channel is rubbed to be cores of paper rolls through the rotating upper rewinding roller. According to the coreless rewinder using the airflow for winding and the winding method thereof, the rotation angle of the upper rewinding roller does not to be strictly controlled in the winding process, so that the requirement for the machining technology is reduced and the machine debugging difficulty is lowered.
